Detangling hairbrush

ABSTRACT

The Detangle hairbrush addresses the problem of removing the tangles from one&#39;s hair without pulling the hair loose from your scalp by moving the bristles in the same direction at the same time in a rapid back and forth motion the bristles will shake the strands of hair loose from the tangle instead of pulling them free from one&#39;s head as in the case of the fixed bristle hairbrush. The hairbrush handle consist of a cylinder or square shaped grip to accommodate the batteries, motor, gears, and pushrod that make up the drive system for the bristle plate. The head portion of the handle has C-shaped channels protruding downward from the long sides of the rectangular shaped head of the handle having the channels parallel and pointing toward the center creating rails for the bristle plate to ride on. The bristle plate is then slid into the rails of the handle and attached to the pushrod in such a manner as to allow the bristle plate to move freely along the rails rapidly in a back and forth almost, vibrating motion therefore shaking the tangle loose instead of pulling it, unlike fixed bristle hairbrushes of the past

BACKGROUND OF THE INVENTION

Everyone with long hair has had the unfortunate task of pulling outtheir hair while trying to comb out tangles. I designed the detanglerhairbrush to address this problem. The detangler hairbrush has movingbristles that stroke in a back and forth motion driven by an electricmotor. This rapid motion of the bristles while being pulled thru tangledhair will separate the strands of tangled hair therefore shaking thehair free from the tangle without pulling it out. Hairbrushes of todaywere designed to separate and shape hair. However hairbrushes of todayhave never addressed the problem of removing tangles without pulling thehair out of your head.

BRIEF SUMMARY OF THE INVENTION

This hairbrush consist of an elongated hallow cylinder shaped handle onone end having a rectangular shaped head on the other end; the headhaving a rectangular top with two 90 degree angle shapes protrudingdownward from the top of the head and running parallel with one anotheron each of the long sides of the head forming a guide for the bristleplate to ride on; The bristles or bristle plate is an arced rectangularshaped thin sheet of plastic or metal having separate rows of stiffbristles protruding downward from the sheet; having each row pointing ina different angle around the arc of the sheet; The bristle plate alsoincorporates a groove at the top of plate running parallel with eachlong edge of bristle plate these grooves will allow the bristle plate toattach to the head of the hairbrush by sliding into the angles or guidesaccommodating for the bristle plate to easily move back and forth; Ateither end of the bristle plate there is an end plate attached acrossthe arc of the plate perpendicular to the grooves; A push rod isattached to one of the end plates and at the other end the rod isattached to a gear that is powered an electric motor in such a way thatwhen the motor is running the bristles and bristle plate will move backand forth in the same direction at the same time in a to and frommotion; On one end of the handle the top portion is removable toaccommodate for dry cell or rechargeable batteries to operate thehairbrush. This invention solves the problem of taking tangles out ofhair without pulling the hair out. In doing so it massages andstimulates the scalp, unlike hairbrushes of today which just pull thetangle out.

DETAILED DESCRIPTION OF THE INVENTION

This hairbrush is comprised of three major parts first being the lowerhandle. The lower handle portion of the hairbrush consist of a hollowrectangular portion at one end and a hollow elongated half cylindershape portion forming into a rectangular shape on the opposite end;having metal contactors on the end of the hollow rectangular portion tosupply current to the drive motor located in the half cylinder. Thedrive motor turns the gear which moves the pushrod therefore moving thebristle plate in a to and fro motion along the guides formed into therectangular head portion of the lower handle; The end of the cylinderclosest to the rectangular head portion of the lower handle extends outto the width of the head portion of the lower handle and is also hollowwith affixed pins to accommodate for the motor, gears, and push rodwhich make up the drive assembly for the bristle plate. The head portionof the lower handle is a rectangular having a convex top having a ninetydegree angles extending downward from both long sides of the rectanglewith the lower sides of the angles pointing to the center of therectangle creating a c shaped groove on each long side of therectangular head portion of the handle acting as guides for the bristleplate to ride on. The upper handle portion of the brush has a hollowrectangular portion on one end leading into a hollow half cylinder shapewhich then widens out to the width of the head portion of the lowerhandle this allows the upper handle to fit snugly over the motor andbattery. The upper handle is removable to allow for batteries to beinserted into the handle. The third part of the hairbrush is the bristleplate. The bristle plate is a sheet of material rectangular shapedaround the perimeter; the sheet is bowed to form an arc across the shortsides of the rectangular sheet; with both short ends of the sheet havingplates permanently affixed to strengthen and hold the sheet in apermanent arc; the long sides of the sheet having c shaped channelsaffixed to the top pointing outward from the center and running parallelwith each other down the long sides of the sheet with the dimensionsbeing such that the channels create a guide allowing one to attach thebristle plate to the hairbrush lower handle. The bristle plate will havea plate affixed to the top of the channels flush around the parameter ofthe channels forming the bristle plate into one piece this plate havinga hole drilled thru it centered at one end to accommodate for the pushrod; the arced side of the bristle plate having straight rows ofseparate cylinder shaped bristles protruding outward from the plate at aninety degree angle having each spaced equally around the arc of theplate. Upon assembling the bristle plate and the hairbrush lower handleone can insert batteries into the handle replace the upper handle andturn on; the drive system in the handle of the hairbrush will move thebristle plate in a rapid back and forth motion causing the bristles tomove in the same direction at the same time creating a vibrating effecton the bristles therefore when the moving bristles are pulled throughthe hair it shakes the tangled strands of hair free from the tangleinstead of pulling them free from the scalp thus encompassing theimprovement over other hairbrushes and hair care appliances on themarket today which just remove tangles by pulling them out.

1. “What I claim as my invention is: by moving the bristles rapidly backand forth in the same direction at the same time, the bristles of thebrush shake the strands of hair loose from the tangle instead of pullingthe hair from the scalp”.
 2. “What I claim as my invention is: the backand forth motion of the bristles against the scalp massages andstimulates it creating a soothing effect on the user”.
 3. “What I claimas my invention is: that this hairbrush can also be made rechargeable”.
